My invention relates to laundry apparatus and more particularly to a device of that character for washing articles of clothing or the like, the principal object of the invention being to provide a device for easily and V in heir respective supports.

Referring more in detail to the drawings:

1 cesignates a rectangular-shaped"tub preferably constructed of sheet metal comprising side walls 2 and end walls 3 having vertical upper portions and converging from substantially half their height toward a bottom lprovided with a drain plug 5} Mounted bet-ween the vertical portions of the walls and substantially mid-way between the ends of the tub is a washer 6 l1l3fiing frame members 7 and 8 secured to the side alls of the tub by bolts 9.

The frame members, preferably of wood, are rectangular in shape, each member being provided with a downwardly extending transverse slot 10 terminating in the lower half of a bearing 11 for a purpose later to be described, the slot dividing the upper half of the frame into paired heads 12. Each frame member is further provided with an inwardly facing recess 18 extending from the bottom of the frame to a transverse line slightly below the bearing 11. On each side of this recess and near its upper end is a deeper and relatively narrow recess 14, communicatin g with a bore 15 extending throughout the length of the head 12.

Each head is provided with a reinforcing cap 16 having depending flanges 17 whereb it is secured to the head with screws 18.

An aperture 19 in the cap 16 aligns with the bore 15 and is adapted to receive the shank of an eye bolt 20, adjustably retained in position by a wing nut 21. Positioned in each bore 15 is an expansion spring 22 provided with a hook at its upper end for en gaging the eye of the bolt 20, the lower end of the spring extending to the slot 14: to en gage a movable bearing member 23 comprising a cross arm 24 having a centrally depending bearing arm 25. The ends of the cross arm are bent outwardly and laterally and are provided with notches 26 for receiving the lower hooks on the springs 22.

It will be apparentthat when the movable bearing member is positioned in the frame member, the expansion springs exert an equal amount of tension on each end of the cross arm. However, by influence of alternate pressure on either side of the depending arm 25, the bearing member 23 may be oscillated, the range of travel being limited by the walls of the recess 13.

Fixed to the lower end of the depending arm and entending laterally and inwardly therefrom is a pivot pin 27 adapted to pivotally mount a supporting plate 28 comprising an oblong end wall 29 having a depression 30' in its upper edge and an outwardly directed depending peripheral flange 31. lntegral with the inner face of the end wall and formed in an arcuate line is a series of bearing bosses 32 for a purpose presently to be described. The center bearing boss extends downwardly forming an integral part of the peripheral flange, and a bearing aperture 33 near the lower edge of the flange is adapted to 'ournal the pivot pin 27.

fn the foregoing description only one of the frame members and its associated parts, including a supporting plate, have been de scribed in detail since one set of parts is a duplicate of the other.

Rotatably mounted between oppositely directed supporting plates 28 and in the arcuate series of bearing bosses thereof, are a series of lower agitating rollers 34 having bearing pins 35 adapted to rotate in the bearings 32.

On the ends of the supporting plates and extending inwardly from the flanges 31 are ears 36, provided with apertures 37. Tie bars 38 secured to the cars 36 by bolts 39 serve to hold the oppositely directed supporting plates with the series of lower agitating rollers rotatably mounted therebetween in a single unit. An upper corrugated agitating roller 40. also preferably of wood, is mounted above this unit by shaft portions 41 and 42 journaled rotatably in the bearings 11 heretofore described.

Tensioning means for yieldingly urging the upper roller in frictional contact with the lower set of rollers comprises upper bearing halves 43 for engaging the shaft portions 41' and 42, the bearings being provided with bosses 44 for receiving the lower ends of compression springs 45, positioned in the slots 10. The upper ends of the springs are restrained by latch members 46 having ears 47 for engaging the lower faces of the reinforcing caps 16, wings 48 providing means for manipulation of the latch members. The shaftportion 41 is provided with a head 49 for limited endwise movement, and the shaft portion 42 terminates in a crank 50 provided with a handle 51 for operating the washer.

Assuming the apparatus to be constructed and assembled as described, its operation is as follows:

Referring to Fig. 3 the crank 49 and corrugated roller 40 which constitutes the driving and agitator element of the apparatus are shown. in clockwise movement and under this condition, the roller 40 frictionally engaging the lower rollers 34 causes tilting movement of the mounting plates on their pivot pins 27 against the tension of the springs 22 which support the bearing members 23 and the lower roller unit. The center roller 34 mounted on the center bearing boss serves as a lever to tip the end plates anti-clockwise on the fulcrum pins 27. The. tilting movement of the plates being in an opposite direction to that of the roller 40 causes a greater contact pressure between the engaging rollers at one side of the mounting plates, whereas reverse movement of the agitator element causes reverse tilting of the lower roller unit and the exertion of pressure on the opposite rollers.

In using the apparatus, an article of clothing or the like, taken from soapy water in the tub, is entered between the engaging rollers 40 and 34 and operation of the crank 49 to and fro induces tilting movement of the lower roller and folding and unfolding of the article as it is shifted from side to side by the roller 40 and the alternate pressure and suction produced by the fluted upper roller in its alternate contact with the lower rollers produces a quick, easy and etlicient cleansing effect.

' What I claim and desire to secure by Letters Patent is:
